A rotary evaporator (rotovap) is a fast and effective method of removing solvent from a flask. A rotovap removes solvent by reducing the pressure within the flask using a vacuum, rotating the sample to increase its effective surface area, and heating the solution. ... Inspect the rotovap and all pieces of glassware to ensure that there are no ...
ADAPTERS, ROTARY EVAPORATORS, VIALS. Adapters permit the connection of standard laboratory dram sample vials directly to the vapor tube or a bump trap of a rotary evaporator. Adapters have a top outer joint of the listed size and a 20-400 G.P.I. thread at the bottom. A PTFE-lined, phenolic, double-threaded connector attaches the vial to the ...
Feb 16, 2019 As you know, rotovap systems use vacuum to reduce the boiling temperature of the solvent. However, the use of vacuum increases the risk of implosion of glassware. In this post, we take a look at the reasons why rotovap implosions occur, the dangers involved, and what you can do to prevent rotary evaporator glassware implosions and ...
Feb 21, 2021 Glass has been the traditional choice for rotovap condensers for 60 years, as it is inert to most chemicals found in chemistry labs. However, glass has a huge weakness when used in condensation: It is a poor conductor of heat, meaning rotary evaporators need flawed solutions to overcome the poor heat exchange of the glass condenser.
Fill the rotovap cold traps with dry ice. Attach a glass bump trap which prevents any solution from entering the main part of the rotovap. Secure with a Keck clip. With a Keck clip attach the flask and bump trap to the adapter portion of the roto-evaporator. Lower the flask into the water bath. This helps to prevent the flask from ...

Jul 11, 2012 Member Is Offline. Mood: Thankful. posted on 24-1-2013 at 03:44. Yamato rotavap glassware set. I bought a Yamato RE400 rotavap with a BM200 water bath on Ebay. I researched it first and found that the RE400 is a discontinued model. I paid $100 (plus $40 for shipping) and got the rotavap and water bath heater both in working condition.
Jun 12, 2016 A typical rotavap uses a variable speed sparkless induction motor that spins at 0- 220 rpm and provides high constant torque. Turn on the aspirator vacuum. On most models, the vacuum on/off control is managed by turning a stopcock at the top of the condenser (left side of the above diagram). Lower your flask into the water bath.

Mar 03, 2022 Hey, guys. S till in Labs Nova channel. Last time, we shared about the skill to repair the equipment and know when it is finished food. Today we will let you know how long the freeze drying food takes to keep the food delicious.
May 19, 2009 Warning: the distillate of habanero is the most contaminating of any we do. The flavor gets into all the glassware and lubricant in the system. The entire rotovap has to be broken down and cleaned in an ultrasonic bath after a habanero run. Because of this we do a lot of it in a row and then don€™t make it for a while.
partially-filled round bottom flask on the ground glass joint of the splash protector. b. Rotate the flask slowly. This will minimize bumping. Wait about 30 seconds. c. Lower the flask into the warm water bath. 9. When the solvent is removed, reverse the steps: a. Raise the flask from the warm water bath. Stop the rotation and open the
